위성공학을 전공하는 학생들에게 실질적이고 경험적인 교육을 제공하기 위해 HAUSAT-1과 HAUSAT-2 두 초소형 위성 개발 프로젝트 기반의 다학제간 우주비행체 설계 교육방법을 적용하였다. HAUSAT-1은 국내최초로 개발된 1 kg급의 초소형 피코 위성이다. HAUSAT-2는 25 kg급의 나노 위성으로 현재 준비행 모델(Proto-Flight Model)을 개발 중에 있다. 이들 설계 프로젝트는 연구와 설계 교육의 통합적 기능을 제공함으로써 대학의 고유기능인 과학 및 기술 연구와 설계 교육을 통한 전문 인력양성의 목표를 동시에 이루는 것이 가능하다. 이러한 복합시스템인 우주비행체 설계 교육을 통하여 참여 학생 전원이 우주비행체의 전 시스템 개발 과정을 직간접적으로 경험할 수 있게 하고, 최근 들어 각광을 받고 있는 다학제간 시스템 교육의 활성화를 이룰 수 있다.

시대변화에 따라 제품에 대한 소비자의 구매 결정기준과 제품 공급방법은 끊임없는 변화가 거듭되었다. 디지털기술을 응용한 on-line 시스템이 상품에 대한 정보를 전달하고 생산과 구매가 동시적으로 일어나는 시장체제가 형성하게 되었다. 그 결과 소비자 중심의 브랜드 구축이 중요한 과제가 되고 있다. 따라서 실증조사를 통하여 경제 사회 환경 변화에 따른 소비자의 의식구조를 파악하고, 이 변화에 따른 소비자의 구매결정 기준을 이해하고자 한다. 소비자의 구매태도를 만족, 선호, 재구입, 추천으로 기준을 설정하고, 이들 4개의 기준에 미칠 수 있는 브랜드 이미지의 요인들의 영향을 파악하였다. 브랜드 이미지의 효율적 형성을 위하여서 생성되는 소비자(고객) 중심의 브랜드 가치는 실증분석을 통하여 얻어진 결과를 보면 사회생활가치, 정서가치, 개성적가치 수용하여 브랜드이미지에 적용하는 것이 효과적인 것으로 나타났다. 연구결과에서 도출된 브랜드 이미지의 공통적 요인으로는 차별성가 고객 중심의 일관성 및 개성적, 감성적 요인들을 부각 시를 수 있는 행태로 브랜드 이미지화를 도모할 필요가 있다는 결과가 나타났다. 따라서 본 연구는 미래 지향적이고, 소비자에게 인지 연상되는 기능을 보다 효과적으로 증대시킬 수 있도록 고객 중심의 브랜드 창출을 위한 가이드라인을 제시하였다.

We investigated the dielectric and mechanical properties of ceramic polymer composite xBNT - (1-x)LCP (x= 0, 10, 20, 30, 40 vol.%). The disk shaped BNT ($BaNd_2Ti_4O_{12}$) - LCP (liquid crystal polymer) composite samples were prepared by compression molding method. With increasing the BNT content in composites from 10 to 40 vol.%, the dielectric constant increased but the dielectric loss as well as bending strength of composites reduced. These composites were well described with modified Lichtenecker's model having k = 0.392 and 0.303 for the first and second ball milled BNT filled composites, which means that the BNT filler in composites are well dispersed. The dielectric constant of the composite comprised of the second milled BNT ($D_{50}$ = 1.39 um) was higher that of the composite of the first milled BNT ($D_{50}$= 2.45 um), which seems to be related with the different particle size and dispersion of BNT fillers in LCP matrix. The bending strength of the composite containing the second milled BNT was superior to that of the composite of the first milled BNT.

Competition of today's markets get to compete the relationship of one system and another system. Competition in relationship of system emphasis molding of cooperate relationship-strycture between enetrprices and It appears competitiveness enriched effects of enterprices in systems. In the rapidly changing economy and marketing situation, Travel agency got worse management situation of themselves more excessive competitiveness then competitiveness efforts between Tourism Relationship Enterprices. So, Relationship marketing will lays a foundation of new travel agency's environment through competitive of relation to travel agency and travel agency, travel agency and hotel or travel agency and airplane. This study's object are present relationships between travel agency and travel relation enterprise of cooperation, complication and competitiveness to relation form. And this study are presents suggestion to generate of hereafter travel relation enterprise through study on relationship with hotel and airplane. A final object of this study are presents a model applys relation method of travel agency and travel agency, hotel and airplane through inspect to specialist analysis. In the result of study, Travel agency are low position and difficult with hotel and airplane at the cooperation but acually It's difficult with travel relation enterprise. So, Travel agency will be operates characteritic system and regulations for win with travel relation enterprise for efficiency of working more than hotel and airplane. Airplane is the best big travel relation enterprise. So, The most airplane has to high cooperate with travel agency. That's why airplane keep going close cooperation with travel agency. Travel agency has to close cooperate with hotels secondly through marketing, exchanging information and union advertisement etc. Hotels are low in complications than travel agency but high in complications than airplane. Although travel relation enterprise are different system individually, because of all of us working with union object, Travel agency and travel compliment-cooperation relationship.relation enterprise has to autonomy behavior with close cooperation through.

Statement of problem. Collarless metal ceramic fixed partial dentures(FPDs) had an esthetic problem such as opaque reflection in cervical region. To overcome this, modified coping which removed its facial cervical metal could be used. The marginal quality could be worsen according to the amount of its facial metal reduction. Purpose. The purpose of this study was to evaluate marginal fits of collarless metal ceramic FPDs with retainers of modified copings. Material and method. Dentoform maxillary left central incisor and right lateral incisor were prepared for 3-unit collarless metal ceramic FPD and fixed in yellow stone. This model was duplicated to PBT resin dies via CAD/CAM and injection molding. Four different facial margin design groups were investigated. Group A was a coping with a thin facial metal collar, group B was a collarless coping with its facial metal to the shoulder, group C was a collarless coping with its facial metal 1 mm short of the shoulder, and group D was a collarless coping with its facial metal 2 mm short of the shoulder. Seven collarless metal ceramic FPDs per group were fabricated. They were cemented to PBT resin dies with resin cement. After removal of pontics, each retainers were separated and observed under Accura 2000 optical microscope. Then, retainers were embeded in orthodontic resin and cross sectioned faciopalatally. Internal marginal fits of midfacial porcelain margins were observed under FE-SEM. Result and conclusion. Within the limitations of this in vitro study. The following conclusions were drawn. 1. Mean marginal gaps of collarless FPDs were in the $50-60{\mu}m$ range. 2. In midfacial margin, marginal discrepancies were greater in group A than in the experimental groups(p<0.05). 3. In midpalatal margin, marginal gaps were greater in group C and D than in group A and B(p<0.05). 4. Marginal fits of porcelain margins were better than those of metal margins in collarless metal ceramic FPDs. 5. In both teeth, internal marginal gaps of group C and D were greater than those of group A and B(p<0.05).
